Thanks for your comments Tom. By the way, an excellent book (Energy From The Vacuum) for any ZPEnergy readers who haven't obtained it yet.
Does the 'Kawa Magnetic Rotary Engine' Patent US5436518 pre-date Minato's Patents? I haven't had the opportunity to read Minato's Patents yet, but it sounds as though these claimed efficiency gains and cool running may also be obtained by not reversing the direction of current in the stator coils as per conventional electric motors. Perhaps also only driving one phase at a time instead of two or three, and with a different arrangment of permanent magnets on the rotor?
Certainly excellent news if Minato's Motors do achieve more work output than that input. If so, it can only be due to Zero Point Energy, as Classical Physics has no explanation.
Hopefully there will also be positive news shortly on the projected release date for the commercial Motionless Electromagnetic Generator?
